I just recently formatted and reinstalled Windows 10 x64. I have not
updated anything related to Cygwin and everything version-wise is just
as it was.

I was previously starting X with the following:

$ xinit -- -multiplemonitors -multiwindow -clipboard -noprimary -dpi 96
-nolisten tcp -displayfd 3 3>/c/home/.display

But now it fails to open the display:

This log doesn't exactly match that command ('-nolisten inet6' rather '-nolisten tcp')

Note that since 1.17.0, -nolisten tcp is the default.

This seems to indicate that the helper clients can't connect to the X server on the (emulated) unix domain socket, which is causing the X server to be stopped.

I can't reproduce this.

Conceivably, this might be caused by firewall issues.

I can get around this issue by using "-listen tcp" instead of "-nolisten
tcp" but I don't understand why. This is especially ironic considering

Can you show the log for a working X server as well, please?

that this is the complete opposite workaround to what I had to use three
years ago:
